GPT-5.4 Mini
GPT-5.4 Mini brings good performance to cost-sensitive workflows.
Strengths
- Over 2x faster than GPT-5 Mini. Low latency makes it responsive for interactive coding and agentic loops.
- Reliable tool use. Handles multi-step agent workflows, subagent delegation, and screenshot-based computer use.
- Strong multimodal understanding. Processes images and screenshots well for its size.
Limitations
- Not a frontier model. For more difficult problems where peak intelligence matters, GPT-5.4 is the better pick.
- Smaller capacity for long, open-ended reasoning chains compared to the full-size model.

GPT-5.4 Mini has access to all agent tools when used with Cursor including:
Find files by name, read directory structures, and grep for patterns.
